When I parallel two 120volt generators together into a 50 amp 4 pin plug do I get two 120 volt legs that are in phase or do I get two 120VAC legs that are 180 out of phase which would result in 240VAC being available on the outputs of the 50amp connector. If the two legs are in phase, are they locked together with no phase difference so they will no fight if they are connected to the same circuit?
